Abstract

A heat-mouldable compsn. contains (a) a starch component, (b) a biodegradable polyester, and (c) a salt of a hydroxycarboxylic acid. Pref. (a) the starchy component is partly melted, and is a native, natural or hybrid starch, from corn, high-amylose corn, waxy corn, wheat, rice, peas, potatoes, manioc and/or cuts or fractions from these, or may be modified, chemically, esp. by ionic or nonionic etherification, esterification, reticulation, oxidn., alkaline treatment, or acid hydrolysis, and/or enzymatically. (b) is polylactic, polyglycolic, polyhydroxybutyric, polyhydroxypropionic, or polyhydroxyvaleric acid, or copolymers of these, or derivs. or salts of the (co)polymers. Esp., it is polylactic acid or a polylactate, e.g. Na polylactate, partic. a polymer or oligomer based on D- and/or L-lactic acid, with mol.wt. below 1,000-000 (below 150,000), esp. an oligomer with mol.wt. 500-5000, and salts, e.g. Na salts, of the polymers and oligomers. The ratio by wt. of (a):(b) is 99:1-1:99 (80:20-50:50), as dry matter. The mol.wt. of the polyester, esp. of lactic acid or a salt, may be at least 150,000. If the mol.wt. of the polyester is below 150,000, the ratio by wt. of (a):(b) is pref. 99:1-70:30, and if it is below 50,000 (800-3000), the ratio is 98:2-80:20. (c) is of a monohydroxy/monocarboxylic and/or polyhydroxy/monocarboxylic acid, esp. an alkali(ne earth) metal salt of lactic (pref.), gluconic, maltobionic, lactobionic or glyceric acid, partic. Na lactate. The ratio by wt. of (a) + (b) : (c) is 99:1-25:75 (98:2-40:60), as dry matter.
